This is an alternative example project. It is largely based on the "explore" example project but has been recreated with slightly different structure.
The intention is that this example will ultimately provide a
slightly different experience. This will include more mapping (possibly
using leaflet), new template (e.g. bootstrap 4) and different navigation.
Build docker image. This will use the settings in teh .env.example file, which can be replaced by creating a ".env" file before building the image (eg. cp env.example .env).
# Get source code
git clone https://github.com/alaw005/django-multi-gtfs.git
cd django-multi-gtfs/examples/gtfsproj
# Build image
sudo docker build -t multiproj .
Run docker container as background (to run in forground change "-d" to "-it". This will automatically run the development server using the settings in the .env.example file.
# Create container
sudo docker run -d -p 8000:8000 --name multiproj1 multiproj
Now setup database and superuser, refer management commands below. This is only required if database does not already exist or multgtfs has been updated (in which case need to migrate only)
# Setup database (if required)
sudo docker exec -it multiproj1 ./manage.py migrate
sudo docker exec -it multiproj1 ./manage.py createsuperuser
Now you can access from browser using host IP address and port 8000.
You can run django management commands as follows:
sudo docker exec -it multiproj1 ./manage.py help
For example, to load a new feed you can do the following (assuming container name is "multiproj1"). NB: The first command copies a file from host system to the container.
cat /host/feeds/feed.zip | sudo docker exec -i multiproj1 sh -c 'cat > /gtfs/feeds/feed.zip'
sudo docker exec -it multiproj1 ./manage.py importgtfs /gtfs/feeds/feed.zip
To specify a feed name rather than the defaul use the following.
sudo docker exec -it multiproj1 ./manage.py importgtfs --name "Feed name" /feeds/feed.zip
At the command line (as long as postgres is installed):
# Create database
createdb -h HOST -p 5432 -U USERNAME multigtfs
# Install postgis extension
psql -h HOST -p 5432 -U USERNAME -d multigtfs -c "CREATE EXTENSION postgis;"
Now initiatise the database using multigtfs:
# Configure database
sudo docker exec -it multigtfs ./manage.py migrate
# Create superuser
sudo docker exec -it multigtfs ./manage.py createsuperuser
That's it.
The following applies to Ubunutu
sudo apt-get install -y git python-pip python-virtualenv spatialite-bin gdal-bin
cd ~/
git clone https://github.com/alaw005/django-multi-gtfs.git
# Navigate to project folder
cd django-multi-gtfs/examples/multiproj
# Create and activate new virtual environment (myenv).
# Use "deactivate" to deactivate virtualenv.
virtualenv --always-copy myenv
source myenv/bin/activate
pip install -r requirements.txt
# Create multigtfs tables in database
./manage.py migrate
# Create db.sqlite3, superuser. Enter "yes" to create superuser and
# then enter username and password when prompted (you can leave email address blank)
./manage.py createsuperuser
# Run
./manage.py runserver 0.0.0.0:8000
Now you can access from browser using host IP address and port 8000.
You can either set environment variables in the .env file as per above or directly at command line when you create the container. For example, to use existing postgis database:
sudo docker run -d -p 8000:8000 --name multiproj1 -e DATABASE_URL=postgis://USER:PASSWORD@HOST:PORT/DBNAME multiproj
The environment variables you can change are identified in the following file:
django-multi-gtfs/examples/gtfsproj/gtfsproj/settings.py
They all use the config() function e.g. SECRET_KEY is set in the following example, indicated by the "config('SECRET_KEY'" section.
SECRET_KEY = config('SECRET_KEY', default='+$8pgzf)luxklr(rhzg4!$6+b^2hbw*-frvh_2-7an9-_==n_u', cast=str)
